multiprocessing-2.6.2.1.tar.gz 目测是支持python 2.x下运行的包, 而你的python 是3.x 要改为相应的版本才行如下例中$ python Python 2.7.12 (default, Nov 20 2017, 18:23:56) >>> print 'test' test 语法区别:$ python3 Python 3.5.2 (default, Nov 23 2017, 16:37:01) >>> print 'test...
1.执行一个python的multiprocessing.Pool进程池程序,实现多进程程序,代码如下,结果在windows下执行报错,但是在linux和unix里面执行没有报错? from multiprocessing import Pool import time ,os ,random def worker(msg): t_start = time.time() #获取当前系统时间,长整型,常用来测试程序执行时间 print("%s开始执行,...

解决方法 将所有与paddle相关的模块都放到 multiprocessing 里 import 且不要在多进程外有 import 这些模块就可以正常运行了,这样在进程结束后相应的资源也会自动释放。 # process 1 def paddle_predict(quene): #将paddle所有相关库都放入进...

Pickle module can serialize most of the python’s objects except for a few types, including lambda expressions, multiprocessing, threading, database connections, etc. Dill module might work as a great alternative to serialize the unpickable objects. It is more robust; however, it is slower than...
